Response to Paper Critiques

The criticism is largely centered on which colors we used, namely their luminance and contrast. The criticism is based on a misunderstanding or misreading of our paper.

We have two responses:

Target and distractor colors were selected randomly for each trial and fully counterbalanced; every target color was also used as a distractor. Color and/or luminance pop-out, and discriminability differences between targets and distractors do not explain the results. Rather, grouping modulates search efficiency: Here is a demo.

Color and luminance contrast explanations do not explain our results for motion. Here is a demo.
